* Improve code examples across multiple lints [#5664 ](https://github.com/rust-lang/rust-clippy/pull/5664 )
### Others
* Introduce a `--rustc` flag to `clippy-driver` , which turns `clippy-driver`
into `rustc` and passes all the given arguments to `rustc` . This is especially
useful for tools that need the `rustc` version Clippy was compiled with,
instead of the Clippy version. E.g. `clippy-driver --rustc --version` will
print the output of `rustc --version` .
[#5178 ](https://github.com/rust-lang/rust-clippy/pull/5178 )
* New issue templates now make it easier to complain if Clippy is too annoying
or not annoying enough! [#5735 ](https://github.com/rust-lang/rust-clippy/pull/5735 )
